A big, finished TL by Max Sinister starting with Genghis Khan's early death in 1200 and ending in the year 1993, it covers events world-wide, although it's still a bit Europe-centric, admittedly.

Its name comes from the Chaos theory-related Butterfly Effect which slowly spreads through Eurasia and later the rest of the world. Well, partly that; partly because I wanted to create an antagonist for a GURPS Infinite Earths setting, which should be different than the Centrum TL which I find somewhat improbable; partly because in the second half of the 20th century many areas in the Third World fall into, yes, chaos; and partly because I had no better idea for a name.

The idea for it was around since the time of the Old Board. However, it took as long as spring 2006 until the TL found its way into the 'net. In August 2007, more than one year later, it was finished.

• Timeline
• Stories
• Scenario

As with Hendryk's Superpower Empire China 1912 TL, there's also a lot of stories for this TL around. The difference: All the stories are written by Max Sinister; and in many cases, the stories aren't really stories but excerpts of books, articles, reviews, forum discussions, commercial ads, and so on. But they also have something in common - hidden references to various members of AH.com. Grey Wolf appears as Gray Wolvertone, court chronicler of New Albion; Thande is mentioned as the Technische Hochschule Argentinien/Neustadt für Delizierung und Eisenverarbeitung, abbrev. T.H.A.N.D.E. (Technical university/college of Neustadt/Argentine for refining and iron processing); ljofa appears as Logo Jedermann; Cathryn Gallant from the Old Board as scandal author Katherine Geller; Leo Caesius inspired the phrase “pulling a Leo”; and the members Ian the Admin, Hendryk, Gladi, hansmeister, POTUS Diffin (as OT-DDR78), David bar Elias, Steffen and Max Sinister himself appear as members of WWW (“Was wäre wenn”, German for WI), TTL's equivalent of AH.com. And there's also a Dieter Waas guy who's very interested in Lesbians…
